Application filed March 22, 1917. Serial No. 156,669.

To all whom/it may concern:

Be it known that we, ALBION D. T. Tuner and HENRY E. Bonenn, citizens of the United States, residing at East Orange and F Newark, respectively, in the county of Es sex and State of New Jersey, have invent ed certain new and useful Improvements in Combined Generators and. Timer-Distributer Bearing-Heads, of which the following is a specification.

In the application ofdynamo electric machines and ignition apparatus to moving vehicles, such as automobiles, it has been found sometimes advantageous to combine at least a part of the ignition apparatus with that of the lighting dynamo and in working out these applications the most usual practice is to make one end of the dynamo electric machine in such a way that a timerdistributer may be operated from suitable drivin means mounted within the head of the dynamo. Usually the portion which carries the timer-distributer driving element is cast integral with one head of the dynamo. ()ur invention is directed to improving, the construction of a combined timer-distributer and generator hearing head so that a very cheap manufacturing construction is obtained.

Where the timer-distributer bearing and housing therefor is an integral part of the head of the dynamo, it sometimes happens that the timer-distributer which is mounted on a driving element extending out of the combination head attached to the dynamo, interferes with some other piece of apparatus such as the carburetor, exhaust pipe, etc., on the engine, and it is another object of our invention to providea timer drive and support which can'be readily adjusted to avoid such obstructions.

A further object of our invention is to provide a timer-drive and mounting which may be readily assembled and disassembled and which will be cheap to manufacture.

Other and further objects of our invention will be apparent to those skilled in the art after consideration of the specification and drawings attached thereto.

In the drawing Figure 1 illustrates an end view of a dynamo showing the timer-distribute]? drive in place. Fig. 2 is a part sectional and elevational view of Fig. 1.

Fig. 3 is a similar view of Fig. 1 but with the timer-drive disposed on the opposite side of the dynamo head.

Referring now particularly to the drawings, 1 is an end plate of the dynamo which is adapted to be fastened to the body by screws 2. 3 is an end of the armature shaft extending through bearing amounted within the head 1. The head 1 has two arcuately shaped bosses 5 and 6 disposed on opposite sides of the center. The end of the bearing plate 1 has a flat annular flanged'surface 7 and a hub 23 machined thereon for the reception of the timer-drive housing 8 having a flange 9 adapted to fit the machined surface 7 and hub 23. The flange 9 has oblong slots 10 and 11 through which screws 12 pass for the purpose of'holding the flange 9 against the machined surface 7 and hub 23. On the outer side of the housing H is a flange 13 having an oblong slot H therein. The flange 13 is adapted to rest on the boss 5,"(Fig. 1)- and is fastened thereto by a screw 15. On the end of the dynamo shaft 3 is'a'driving gear 16 held thereon in any suitable manner, a lockwasher 17 and nut 18 being shown in the drawing. A key in the gear 16 may also be used. Mounted within the housing 8 is a shaft 19 having a gear 20 fastened thereto and adapted to mesh with the gear 16. The shaft 19 extends upward and is adapted to have the usual timer-distributer mounted thereon. Since the timer-distributer itself forms no part of our invention it is not shown or described herein. A grease or oil cup '21 is shown to carry lubricant into the shaft 19 and the gears "20 and 16, which also receive some lubricant through the oil cup 22 in the head 1. i The timer-distributer driving element housing 8 may be rotated about the shaft 3 by loosening the screws 12 and 15 and hence the timer-distributer mounteden the top of theshaft 19 will be caused to take up an angular position with reference to the vertical line through the center of the driving shaft. After the acquired angular movement has been obtained the housing 8 is locked in position by the screws 12 and 15.

Where it is necessary to place the timerdistributer on the right hand side of the be used in both cases and only right and left hand timer housings are required; hence from a manufacturing standpoint the cost Yof production is materially reduced for the reason that the bearing head 1 becomes universal for all dynamos of the particular size to be used and only right and left hand timelf housings which are very small and inexpensive parts need be" carried in stock.

It will thus be seen that by our construction we have simplified and reduced the cost of manufacture of devices of the class described and while we have shown one form of our invention we do not wish to be limited to the exact construction shown, as various changes may be made in the details, as for example, the head 1 may be slotted for screws 2 so as to permit the whole head to be turned about the center, if desired.

Furthermore in some cases it may be found advantageous to fasten a connecting arm with some portion of the timer housing, such as the fla'n e 13, and then join the connecting arm widh the spark advance lever 'ivhereb% the timing of the spark is con- 30 trolled y shifting the timer housing itself.

Having thus described our invention what we claim is 1. In combination, a generator of electric current havingan armature shaft extension and a driving member thereon, a bearing head for the generator having a projecting hub and a bearing for said armature shaft therein, a housing having an annular flange fitting around said hub and an extending flange to engage a part of the outer surface of said bearing head, a timer distribu'ter driving element mounted within said housing and adaptedto codperate with the driving member on the shaft extension, coacting means between the housing and bearing head consisting of slots in said.

flanges R and screws passing therethrough into said bearing head for adjusting the angular position of the housing and driving element'on said bearing headand for allowing saidhousing and driving element to be quickly removed from said bearing head.

2. In combination, a generator having a shaft extension and adriving member thereon, a timer distributer driving element having a part adapted to engage the driving member on the generator shaft extension, a bearing head for the generator having a bearing therein for the generator shaft, a housing for both said driving member and said driving element, co-acting means between the said housing and bearing head for adjusting the angular position of the housing and driving element on said bearing head, and means for adjusting the entire bearing head about the generator shaft.

3.' In combination, a generator having a shaft extension and a driving member thereon, a timer-distributer driving element having-a partadapted to engage the driving member on the-generator shaft, a housing for the said driving element and said driving member, a bearing head for the generator having a plurality of bosses thereon for the purpose of receiving right or left hand housings for the timer-distributer driving element and means for adjusting the angular position of said housing on said head.

4. In combination, a generator of electric current having an armature shaft extension and a driving member thereon, a bearing head for said generator armature shaft, said head terminating in a centrally located annular flange and hub extending from the flange, bosses on said head on opposite sides of the center and near the edge and terminating in'the same plane. as said flange, a timer-distributer driving element and a housing for the same adapted to fit on said flange, hub and bosses to the ri ht or left of the said shaft as required, sai timer-distributer driving member adapted to be driven by the driving member on the generator shaft, and means for adjusting the angular position of the housing on the driving head.

In witness whereof we afiix our signatures.
